sql server - SQL Like operator return null -


when use like operator on column string type, return 0 result there data matches criteria.

even interesting 'ga' return 0 shown in example below.

create table #temppersons (     firstname varchar(255) );  insert #temppersons (firstname) values ('anne daugaard') insert #temppersons (firstname) values ('jenne neergaard') insert #temppersons (firstname) values ('mark daugaard') insert #temppersons (firstname) values ('hans daugaard') insert #temppersons (firstname) values ('alle daugaard') insert #temppersons (firstname) values ('kent daugaard') insert #temppersons (firstname) values ('mavi gilbeert')  select * #temppersons  firstname '%ga%'  if object_id(n'tempdb..#temppersons', n'u') not null    drop table #temppersons;

no result when firstname 'ga', when firstname 'gaa' or 'daugaa' there hits.

is 'ga' special?

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
